BRAKE-BEAM FULCRUM.

astener.

fibell whom it may concern: "Be it known that I, GEORGE Vicron TQM- t'iIN, a, subject of the King of Great Britain, residing at, Cleveland, in the county of Guyahoga and State of Qhio, have invented certain new and useful improvements in YErakeQBeam Fulcrums, of which the following is a specification. "*fdhehbject of my invention is to elimi- X natethe tendency to. split thefulcrum memhers apart by the brake beam member seated between them, by having the plane of connectien between the members intersecting the, plane of the tension member; and with it these and other objects in view, my invenition consists of the parts and combination of parts as will be hereinafter more fully set forth;

"in the drawing Figure l is an elevation of a' tlillssed brake beam showingone of my improved fulcrums or struts secured thereto; Figs; 2 and 3 are enlarged 'detail elevations or my improved fulcrum at right angles to each other, and Figs. 4 and 5 are enlarged W detail elevations showing another embodiment of my improved fulcrum or strut.

The reference numeral 1 designates the compression member and 2 the tension menibejrof the brake beam, to which is secured at each end a'brake head 13 of approved construction. :The strut or fulcrum is preferably a single forging having two members 3 and 4 bulged intermediate their ends for the passage of a brake lever which is pivoted therebetween on a bolt which passes through the bolt openings 5. Iminediately below the bulged portions, the members 3 and 4 are brought together and secured by means of a rivet 6. The lower 30 end portions of the members 3 and 4 are de- 'fiected at substantially right angles to the plane of connection between the members 3 and 4, and are formed to the configuration of the tension member 2 and con stitutc seats 7 and -8 for said tension member, the plane of connection between the members 3 and t intersecting the plane of the tension memher, so that the tension member has no tendency whatever to split the fulcrum in the plane of tcon nectioii of its members 3 and 4. In order to rigidly secure the strut to the compression member 1, which in the present instance is shown as an angle bar, but might just as well be a channel between the two 5 sides of= which the head 11 0f the strut fits Patented July 3, lull-5.

Application filed July 17, 1914. Serial No. 851,510.

snugly, aclip or brace 9* is laid around the compression member, so that the latter is clamped between the clip and the head 11 of the strut. lhis head is formed in the bend between the two members or legs 3 and 4, which are turned sharply inward without meeting to form a neck, so that a space, as at 12 is formed between the mem bers 3 and at. A bolt 10 is drawn through the ca rs of the clip 9 and the spaced portion he of the members 3 and 4. This spacing 12 will make the joint more secure than if the head and neck were solid, as, on account of the flexibility of the head and neck the bolt and nut 10 may be drawn up tighter.

It will be seen from the construction shown in Figs. 1, 2 and 3, that by reason of the fact that the plane of connection between the members. 3 and l intersects the plane of the tension member, no work is imt5 posed upon the rivet 6 other than to normally hold the members 3 and 4 together, the work imposed on the fulcrum by the tension member being carried entirely by the tension member by reason of the fact that the plane of connection between the two members intersects the plane of the tension member.

In Figs. 4 and 5, l have shown another embodiment of my invention wherein the st ends 9 and 10 of the fulcrum members 3 and 4 are deflected toward each other and the lower end portions of the members 3 45* are each provided with an opening 11 constituting the seat for the tension mem her 2. As in the other constructions above described, the plane of connection between the members of the fulcrum intersects the plane of the tension member, thus eliminating all tendency of the tension member to split the fulcrum.

I claim 1. A fulcrum or strut for brake beams comprising a single forging having two members integral at one end, and having me.

tension member bearings at their other ends and connected together near the tension member bearing and having the plane of connection intersecting the plane of the tension member, said tension member bearrot ings being formed by bending the end of the forging transversely to said plane of connection. 7

2. A strut for brake beams comprising a double bent strap,- the bend forming an we 5. A strut for brake beams comprising a abutment head against the compression member, a neck under said head formed by the spaced sides of the strap, and means including a tension bolt through said neck for securing 'thestrut to the compression member. 1

3. A strut for brake beams comprising a double bent strap, the bend forming an abutment head against the compression member, a neck under said head formed by the spaced sides of the strap, and means including a tension bolt for securing the strut to the compression member, and a clip embracing the compression .member and said neck, said tension bolt being drawn through said neck and the ends of the clip.

4. A strut for brake beams comprising a double bent strap, the bend forming an abutment head against the compression member, a neck under said head formed by the spaced sides of the strap, and means including a tension bolt for securingtthe strut to the compression member, and a clip embracing the compression'member and said neck, said tension bolt being drawn through said neck and the ends of the clip, thereby securely clamping the compression member between said head and said clip.

double bent strap, the bend forming an abutment head between the sides of the compression member, a neck under said head formed by the spaced sides of the strap, and means including a tension belt for securing the strut to the compression member, and a 1 clip embracing the compression member and said neck, said tension bolt being drawn through said neck and the ends of the clip,

thereby securely clamping the compression member between said head and said clip.

6. A strut for brake beams-comprising a GEORGE VICTOR TOMLIN.
